Nonclassic boundary value problems in the theory of irregular systems of equations with partial derivatives

Nikolai Sidorov, Denis Sidorov

The linear PDE $\mathbf{B}\mathbf{L}(\frac{\partial }{\partial x})u={\mathbf{L}}_1(\frac{\partial }{\partial x})u+f(x)$ with nonclassic conditions on boundary $\partial \Omega$ is c…
